The first occurred just before 3 p.m. in the town of Richland. State police said a 1990 Harley Davidson driven by Gary R. Schipper, 70, of 73 Darrow Road, New Haven, crashed into the back of a Toyota Camry stopped at state Route 13 and county Route 2A. The Camry was driven by Mary S. Cheney, 57, of 168 Wheat Hill Drive, Sandy Creek.

State police said Schipper suffered arm and leg fractures. A helicopter took him to University Hospital, where he was in serious condition Sunday night.

His wife, Ann R. Schipper, 67, went by ambulance to University Hospital with a broken leg.

Cheney was not injured, troopers said, and no tickets were issued.

The second crash took place a half hour later in the town of Redfield. There, a man lost control of his 2006 Harley on Teachout Road, near county Route 27.

Oswego County sheriff's deputies said Nicholas Santora, 65, of Marsden Road, Mexico, missed a curve and crashed his motorcycle into a guard rail. An ambulance took Santora to University Hospital, but his condition was unavailable Sunday night.

His passenger, Laurie Wakeman, 45, appeared to suffer more severe injuries and was flown to University Hospital. She was in fair condition late Sunday, a nursing supervisor said.

Deputies said both were wearing helmets and their injuries were not considered life-threatening.
